OTC 7368 Torque Multiplier, 3/4" Input to 1" Output, 2200 lb-ft Capacity
- The OTC 7368 Torque Multiplier is a mechanical torque-enhancing tool that amplifies input force while reducing user effort. With a 3.3:1 gear ratio and friction losses accounted, it converts up to 730 lb-ft input into a 1-in drive output of up to 2,200 lb-ft.
- Features:
- 3.3:1 gear ratio multiplier with only about 6% frictional gear loss for efficient torque transfer
- 3/4-inch drive input interface (max 730 lb-ft) paired to 1-inch drive output
- Compact head width (3.6 inches) and integrated reaction bar (15-5/8 inches) for stable application
- Sturdy construction with included reaction foot to resist rotational forces during use
- Specifications:
- Manufacturer: OTC (Bosch Automotive Tools)
- Part Number: 7368
- Input Drive: 3/4-inch (max 730 lb-ft)
- Output Drive: 1-inch (max 2,200 lb-ft)
- Head Width: 3.6 inches
- Gear Ratio: 3.3:1 (multiplier)
- Reaction Bar Length: 15-5/8 inches
- System Compatibility / Application: Ideal for tightening or loosening heavy fasteners such as differential nuts, suspension bolts, and frozen lug nuts-where direct torque wrench capacity is insufficient

The OTC 7368 Torque Multiplier is also referred to as OTC 7368 torque wrench multiplier, high-torque multiplier tool, 3.3:1 torque booster, and heavy-duty torque multiplying wrench.
The OTC 7368 Torque Multiplier lets technicians amplify their applied torque reliably, converting modest input torque into high output force (up to 2,200 lb-ft) for heavy-duty fastening and removal tasks.
Q: Why is it often labeled 2,000 lb-ft?"
A: Some listings market it under "2,000 lb-ft" as a rounded figure, but the actual rated output is 2,200 lb-ft when input is 730 lb-ft and accounting for gear efficiency.
Q: What gear ratio does it use?
A: It uses a 3.3:1 mechanical ratio, meaning for each unit of input torque the output is amplified 3.3 times, minus ~6% frictional loss.
Q: What size input and output drives does it support?
A: The input interface is 3/4-inch (capable of handling up to 730 lb-ft), and the output is a 1-inch drive for heavy torque applications.
